To be fair, what's on it still works, at least as far as I could tell.
Just that I get quite uncomfortable not knowing what/why am I seeing
errors when I use tc to display the qdisc stats and I don't know if
just doing a filter match on dport 80 is enough or should I use the
often found method of marking in iptables and filtering on the mark.

Actually using pfsense was my original intention after reading up on
some past discussion here. Except I didn't realize I couldn't run
pfsense on top of a normal CentOS distribution and I don't have the
option of putting another machine in that particular setup for a
dedicated router/firewall box.
